This figure's daughter Be
This figure's daughter Benthesikyme rescued and raised his son Eumolpos. Zeus convinced a group of centaurs to trample to death a figure once raped by this deity, who changed that maiden into the invulnerable male warrior Caeneus after ravishing her. This figure's tryst on the floor of Athena's temple convinced Athena to turn Medusa into a hideous Gorgon. This deity loses a contest to Athena after she creates the first olive tree, making her the patron of Athens. He had sons like Polyphemus and Triton, who could control the waves with a conch shell. For 10 points, name this wielder of the Trident, the Greek god of the sea.
